An electronic device may include an ambient light sensor that measures ambient light color, a projector that projects ambient-light-matching illumination onto a surface, a user input device such as a microphone that gathers user input, and a position sensor that measures a position of the surface, a user, and/or a real-world object relative to the device. The ambient-light-matching illumination may create illuminated regions on the surface that blend in with the surrounding ambient light. Certain pixels in the projector may be turned off to create one or more unilluminated regions within the illuminated regions. The unilluminated regions may form apparent shadows. Control circuitry in the electronic device may adjust characteristics of the unilluminated regions by dynamically adjusting which pixels are turned off based on voice input, gesture input, and/or other sensor data.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The electronic device defined in claim 1 wherein the optical position sensor is configured to measure hand gestures and wherein the shape of the illumination is adjusted based on the hand gestures.
3. The electronic device defined in claim 1 wherein the optical position sensor comprises an array of infrared light emitters and an infrared camera.
4. The electronic device defined in claim 1 further comprising a voice-controlled internet-connected speaker.
5. The electronic device defined in claim 1 wherein the optical position sensor comprises a stereoscopic imaging system.
6. The electronic device defined in claim 1 wherein the illumination forms at least one of: text and a moving object.
7. The electronic device defined in claim 1 wherein the light sensor comprises an ambient light sensor and the color comprises an ambient light color.
8. The electronic device defined in claim 7 wherein the color of the illumination blends in with the ambient light color.
9. The electronic device defined in claim 1 wherein the optical sensor comprises a camera configured to capture images of an object in an environment, the electronic device further comprising control circuitry configured to process the images using image recognition techniques to identify the object in the environment.
12. The electronic device defined in claim 11 wherein the illumination is adjusted in response to identifying the object in the environment.
13. The electronic device defined in claim 12 further comprising a voice-controlled internet-connected speaker.
14. The electronic device defined in claim 10 wherein the light sensor comprises an ambient light sensor and wherein the illumination comprises ambient-light-matching illumination.
16. The electronic device defined in claim 15 wherein the depth sensor comprises an array of infrared emitters and an infrared camera.
17. The electronic device defined in claim 15 wherein the light sensor comprises an ambient light sensor configured to measure ambient light and wherein the color of the illumination is based on the measured color of the ambient light.
19. The electronic device defined in claim 15 further comprising a voice-controlled internet-connected speaker.
